Could this be the ultimate autoX airbox?
Alright, I'm posting this in the little corner because everyone else will think I'm insane, you guys already know I am.
Anyways... we've figured out already that CAIs and SRIs suck your low end up. They're wonderful for high RPMs, problem is you need basically from 3000 up. So, that leaves the stock box right? The restrictive thing with a lawn mower sized filter and huge resonator. Sure you can pull the resonator, but then you're sucking air from the back of the engine bay, the tiny filter is still there, and this isn't too advantageous is it? We're just screwed...
....Or maybe not.
Take a look... I test plopped this in last night.
This could solve most of the problems. First off, its enclosed, so hopefully it lets you keep your low end since it keeps air surrounding the filter. It takes a cone filter already, there are numerous high flow replacements. It fits neatly into the engine bay with the help of a new bracket, only problem being the battery needs to move, but the STS rules permit moving it to the trunk anyways. What it does do, is dump the mouth of the box right behind the inner corner of the headlight, with the possiblity of going straight down, rather than the back of the engine bay. This leaves the issue of getting the existing non-metal tube into the throttle, which some moron at Honda decided to flip up 90 degrees. Well, my busted Injen will work fine for this... cut the top elbow off and thats that. Where did I find this wonder-intake? Right under all our noses, the last place even I thought to look... under the hood of some other car. Its right out of an Integra. Now... I intend to insure that this thing will indeed fit right in. As of now, it looks like it would go no problem, its about the size of the battery, maybe a little wider. but the piping would fit right were the resonator goes, and I just need to stuff the Injen elbow on the end of it. I'll keep you guys in on this.
I do intend on testing this thing throughly. Maybe not on a dyno per say, but by timing it relatively accurately. I've figured out that my video camera can break itself down to about .07 sec intervals. So I intend on pointing it at the cluster, and getting as close as I can to timing out various RPM and speed intervals (I hope the difference is more than .07 sec) to see where and how much it makes a difference. I think just by the substantially larger size of the filter element, it would make a difference, even if it is a stock box (it is rigged up for a B18 and a big ol DOHC head, remember). Lets hope this pays off, or I'm wasting a lot of time and a bunch of money too....

Rep Power: 380 I recall one of my racing friends saying that the old D series engines performed better with the stock air box, with the resinator removed.. By somthing like 4-5 HP Better then CAI and sort ram. (Dyno tested) This was on an old CRX.

Rep Power: 424 But it had an airbox similar to what I want to drop in, not whats already there. Thats the thing. I've seen the filters on the old cars and they're considerably bigger than we got, so more air is running through them.
Basically this ends up as the same thing... stock B-series airbox, no resonator.

Rep Power: 318 I wonder how it will compare to the K&N FIPKII. Thats what I have & it gave more of a midrange pull as opposed to all up top, & I didnt notice any low end drop either. This is of course based on what ive noticed as I havent ridden in many other civics, so I could be wrong, but i think the K&N does what your trying to get out of that. I hope you expirement puts down some good numbers cuz the K&N is probrbly a lot more money so this would be a more practical approach.
Good luck man

Rep Power: 0 maaan i love you for doing this boilermaker.
so basically, you're using the old upper piping from your Injen CAI to go from the TB to the first part of the ITR air tube that leads to the filter in the box. so that box is gonna sit basically where the stock resonator is and have the inlet go straight down towards the transmission? sounds like a great plan tho, actually do-able and makes sense.
keep us posted!

Rep Power: 0 Are you taking the box as well out? (The box on top of the tb) Or are you connecting the plastic bend to the box to suck air from behind the headlight? If you do the second, what about the openning? Are you double filtering it?

Rep Power: 0 You could cut the middle black piece in the box on top of the tb to make it one large passage. Then connect the hose from the box and put a filter on the other end. Are/Can you take the right headlight out to increase air intake?

Rep Power: 424 Guys, just hang on till saturday, I'll explain this all after its in the car.
PS- I got the airbox off ebay for $29.

I've seen that before on a chick's car. Her boyfriend (who was into auto-x) did it for her. This was like last year.
So what you're saying is, it will retain low-end power while adding 4-5 more HP over stock or over an intake?
Oh yeah, and if my memory serves me right, her battery was not relocated. The tube extended all the way to that corner where the stock intake's tube sits. She didn't seem to complain about it, that's for sure.

Rep Power: 424 Holy **** this thing works! Like not just a little either. Doesn't bog the top like the stock box, doesn't bog the bottom like a CAI. This thing is wonderful. Who ever would have thought this would be something that helped... oh well. I'm gonna work on the videos.... might take a few days though, got some other things to do that are more important.
